Larry Ellison, Oracle’s billionaire co-founder, had his net worth cut by $15 billion Tuesday as the company’s stock paced its worst loss in nearly a year, after a recent earnings report that fell short of estimates, though analysts remained optimistic about the database software firm.

After the close on Monday, Oracle reported earnings per share for the fiscal second quarter of $1.47, trailing analysts' average estimate by a penny, according to LSEG. Revenue rose 9% from a year earlier to $14.06 billion, missing the $14.1 billion average estimate.
